SLICING-MACHINE.

SPECIFICATION formng part of Letters Patent No. 508,206, dated November 7,1893.

Application filed .Tuna 25, 1892. Serial No. 437 (NO model) To all -whom it may concern.- A

Be it known that we, THOMAS COLDWELL and WILLIAM H. OOLDWELL', citizens of the United States, residing at ,Newbu-g, in the county of Orange audState of New York, have invented certain new and useful Im:

provements in Slicing-Machines, of which* the;

Fig. 2 is a cross section on the line 2, 2, of

Fig. 1, looking in the direction indicated by the arrow, 1. Fig. 3 is a sectional view on the line 3-3 of Fig. 1, looking toward the rear of the machine. Fig. 4: is a side viewof a slicing maehine embodying other features and forms of our invention. Fig. 5 is a sectional View taken on the line 5-5 of Fig. 4 looking in the direction indicated by the ar- 'row 2. Fig. 6 is a plan view partlyin section indicat'ing a different form of the intermittent cluteh feeding device from that shown in the figures already described. Fig. 7 is a sectional View taken on the line 7-\7 of Fig. 3. Fig. 8 is a cross sectional view of the rim of the weighted Wheel, taken on the line 8-8 of Fig. 2.

The frame-work of the machine co nsists of the front piece A and the trough-like portion -C in' which the article being sliced is placed,

this being supported at its rear end by the standard or foot-piece B. In making this frame we prefer to cast the front piece A and the trough-likesupport. in one piece thereby effecting a saving in the cost of construction. The front piece is formed with the standard 2 rising from one side of the base thereof, and with a cross piece 4: extending from the top of the standard to the other side 3 of the end piece. These portions, 2, 3, and 4:, of the front piece inclose a space above the meat support O, through which neat is fed to be acted upon by the knife.

dis a shaft projecting outward from the `cross piece 4, near its j unction with the standard 2, upon which the wheel E that carries the cutting blade F is mounted. The wheel is weighted upon the same side of its axis as that upon which the knife is situated, for the purpose of assisting in slicing the meat, as the gravity of the Wheel thus weighted acts, as the knife is passing through the meat, to overcome the resistance offered thereby. This Weighting of the Wheel we effect by making that' portionof the rim, 6, which is on the side of its axis opposite the knife, hollow or shellshaped,.-as,at, 7,- F igs, 2 and 8,--while the other portion thereof is so1id. D Figs. 1, 2, and 3 is a feeding screw,- preferably arranged below the support 0,- and G is a sliding feeder for the meat or other article being sliced. The feeder may be of any desired kind, and, when made as shown in Fig. 2,-has a shank or stem 8 which projects through a slot 9 in the .support C and earries a nut I-I that engages with the serew.

The screw shaft is turned, so. as to move the'feeder, by means of our improved intermittent cluteh feeding device, which in turn is actuated by Connections between it and the Wheel.

We will first describe the form of feeding -device shown in Figs. 1, 2 and 7. L is a disk on the end of the screw shaft, and with a flange l projecting from the edge of the disk a cluteh or gripping piece K is arranged to engage. This gripping piece is pivotally securedto a reciprocating rod I, and has two opposed gripping or cluteh faces, k, which are preferably formed by making a comparatively deep and narrow, angular recess K' in one side of the clutch piece, the opposite walls of the recess constituting the gripping or clutchfaces. The reciprocating rod I has at its upper end a strap 71 which surrounds an eccentric J formed with or secured to thehub IOO parallel with the side faces of the fiange of the'disk L they are free to move independently of each other; but when the gripping piece is rocked onits pivot so that the faces k are at an angle at the edgefaces of the disk, then the latter are gripped by the faces la of the gripper;--and so long as they continue in this position, one of the parts cannot move without the other. From this it follows that the spring M, by rockiug the gripping or clutch piece, causes the latter to engage the disk L. It Will now be understood that when the rod I is moved upward it carries the gripping piece with it, and this in turn moves the disk L a partiai revolution, being held in engagement therewith by the spring M. On the other hand when the rod I noves in the reverse direction, it travels in the same direction as-the spring M tends to carry the free end of the gripping piece, and therefore thelatter slides upon the disk without moving it. Under some circumstances gravity might be depended upon to keep the piece K in proper engagement with the disk, but ordinaril'y we prefer to use the spring.

In order that the extent of the movement imparted to the shaft by the intermitting feed device just descrihed may be re'gulated, we make use of an adjustable stop, whereby the effective movement of the clutch or gripping piece may be varied. This stop consists, by preference, of a screw N having a bearing in the clutch piece K, and arranged so that its end comes in contact With a stop or abutm ent O projecting from the frame of the machine, andthereby arreststhe backward motion of the free end of the gripping piece to a greater or less extent. It will he seen that when the end of the screw N,--upon the downward movenent of the rod L-comes in contact with the stop O, the free end of the piece K is stcpped while the end connected with the rod continues to move forward,--thus resulting in rocking the piece backward against the action of the spring until its grip upon the disk L is released. On the return or upward movement of the rod the clutch or gripping piece remains inactive and does not grip the disk to move it until the screw leaves the abutment The sooner,-in the downward movement of the rod I,-the screw comes in contact with the stop or abutment, the greater will be the extent of the inactive movement of the gripping piece, and the shorter willbe the movement imparted to the screw shaft.

It will be evident that the screw might be mounted in the abutment, and be arranged to bear against the end of the piece K.

In Figs. 4 and 5 we have shown ourimproved intermittent adjustable feeding device applied to a slicing machine having a feeder for the meat different from that heretofore described. In this figure D' represents the shaft upon which the wheel E is secured. It extends over the meat support C, and is mounted in bearings in the front and rear end pieces, A and B respectively. The meat or other article tobe sliced is t'ed forward by a vertically arranged feeder P having teeth which project through an Opening or openings Q in the side wall of the support C. L' is the disk arranged at the upper end of the shaft of the feeder P, and K' is the clutch or gripping piece which engages with the edge thereof. This piece is pivotally secured to the rod 1', which is provided with a strap j that surrouuds an eccentric upon the shaft D'. M' is the spring which tends to move the free end of the piece K' inward or backward, and N' is the adjusting screw by which the eective novement of the gripping pece s regulated. This intermittent clutch feedng device operates substantially as does the one shown in Figs. 1, 2, and 7, and need not therefore be described in detail.

In Fig. G the disk L which is adapted to be applied to the feed screw shaft D is shown without the fiange l, the clutch or gripp ng piece K engaging with the edge of the dsk itself; This construction pcrnits the disk and the piece K to be mounted at right angles to each other instead of their being in substantially the same plane,which under certain circumstances may be desirable. The cluteh disk L' shown in Figs. 4 and 5 is similarly arranged, relatively to the shaft to which it is applied, and to the internittent gripping device which egages the'ewith, to the clutch disk L shown in Fig.-6.

It will be evident that the intermittent clutch or gripping feeding device which we have invented and herein described, may be used upon otherkinds of machines than slicing machines where avariable feed is desired.

Without limiting ourselves to the precise construction and arrangement of parts shown, what we claim is-- 1. In aslicing-ma'chine, the combination of the knife, the feeder which advances the article to be sliced toward the knife, and the hereindescribed intermittent clutch feeding device, connected with thefeeder, and consisting of the disk, a clutch piece whichengages with the disk, the reciprocating arm to which the clutch piece is pivoted, an adjustable stop with which the clutehpiece engages directly, at each of its movements, and a driving connection for the reciprocating arm by which it is moved an invariable distance at each reciprocation, substantially as set forth.

2. In a slicing machina, the combination of the revolvin g knife, the feeder which advances the article tobe sliced toward the knife, an eccentric mounted upon the shaft which carries the knife, a reciprccatingrod provided with a strap which closely surrounds the said eocentric, a clutch or gripping piece pivoted to the rod, a disk connected with the said feeding device and with which the gripping piece engages, and an adjustable stop carried by some stationary part of the machine with which the said gripping or clutch piece engages as itis moved, substantially as set forth.

3. In a slicing machine, a wheel to which ICO the revo1ving knife is secn'ed, having thafq ing and hving feeding projections which ex-.. 1 portion of its rin which is 'on the sidejof its tend through the same to engage with the v axis opposite to that 'on which the knife is article, and means for revolving the feeder,
